Bug with mandatory fields in tabs : GXT 2.2.5 (build 2479)

Hello,

We have a problem when we use a window with few tabs and mandatory fields.
We have coded a specific class to show our problem (see “WindowMandatoryError”).
In this example, we have two tabs. We have a mandatory field in the second tab. The value of this field is already assigned with a “setvalue”.
When we open the “WindowMandatoryError” and click on “submit” we can see that the “home” field is not valid even if the value is already assigned.
If we click on the second tab and then on “submit” at this time the “home” field is valid.
This problem comes from the “render” property of the field. When we are on the first tab, the render property is false and in this case the getRowValue returns “” (empty string).
